重要的是理解霍夫圆变换过程:https://en.wikipedia.org/wiki/Circle_Hough_Transform
import cv2 as cv im = cv.imread(‘../result_25k.png‘, cv.IMREAD_COLOR) im_gray = cv.cvtColor(im, cv.COLOR_BGR2GRAY) im2 = cv.medianBlur(im_gray, 5) circles = cv.HoughCircles(im2, cv.HOUGH_GRADIENT, 2, im_gray.shape[1] / 8, 100, 130, minRadius=0, maxRadius=0) print(circles) for i in circles[0, :]: cv.circle(im, (i[0], i[1]), 1, (0, 255, 0), 2) cv.circle(im, (i[0], i[1]), i[2], (0, 128, 255), 2) cv.imshow(‘im‘, im) cv.waitKey(0) cv.destroyAllWindows() cv.imwrite(‘../result.png‘, im)
opencv 调参没什么意义,仅对我使用的图像有用。
